What is the probability that the birthdays of five persons chosen at random will fall in twelve different calendar months?
The probability that the birthdays of five persons chosen at random will fall in twelve different calender months is zero. You would need at least twelve persons to have a non zero probability.
What is the probability that your birthday will fall on Saturday or Sunday?
2/7, as there 7 days in a week.
What is the probability of at least one birthday match among a group of 41 people?
The probability of at least 1 match is equivalent to 1 minus the probability of there being no matches. The first person's birthday can fall on any day without a match, so the probability of no matches in a group of 1 is 365/365 = 1. The second person's birthday must also fall on a free day, the probability of which is 364/365 The probability of the third person also falling on a free day is 363/365, which we must multiply by the probability of the second person's birthday being free as this must also happen. So for a group of 3 the probability of no clashes is (363*364)/(365*365). Continuing this way, the probability of no matches in a group of 41 is (365*364*363*...326*325)/36541 This can also be written 365!/(324!*36541) Which comes to 0.09685... Therefore the probability of at least one match is 1 - 0.09685 = 0.9032 So the probability of at least one match is roughly 90%
If 5 distinct dice are rolled what is the probability of getting at least one 6?
You must notice that it is easier to find the probability that none of the dice are six. This is the complement of the answer. Pc= (55)/(65) = .4019 *the first die has 5 ways to not equal six, and so on for the remaining dice. [55] outcomes have no six. *the total number of outcomes gives each die 6 ways to fall. [65] outcomes overall. *Probability is the favorable outcome divided by the total number of outcomes. *Probability of an event is 1 minus the complement of the event. P = 1 - .4019 P = .5981 <<<<<<FINAL ANSWER
Two coins and one six sided cube are tossed together What is the probability of getting 2 heads and a four?
Probability is defined as the number of ways an outcome can occur divided by the number of possible outcomes. For the coins, there are 4 outcomes (HH, HT, TH, TT). On the cube, there are 6 possible outcomes. The total number of outcomes is then 4*6 = 24. Since there is only 1 way to obtain HH, look at the cube outcomes. With the HH outcome, the cube would need to fall on a 4. So, there is only 1 way a HH4 can occur. Therefore the probability of getting 2 heads and a four is 1/24 or 0.04167.
What is the probability landscape arch is fall?

Why does an object dropped from a certain height have more than twice the speed of an object dropped from half the height of the previous object?
Because they undergo an acceleration. Free fall velocity is the function of a square.
When you fall down what happens to the skeletal system?
it depends upon the height and distance. if we fall from a height we may get fractures in the bones or severe injuries. if we fall from a less height we may not get such injuries.
What height do you fall from if you fall for 6.5 seconds?
Over 9000.
What is the probability that your birthday next year will fall on a week day?
74 %
What is the probability that the birthdays of five persons chosen at random will fall in twelve different calendar months?
The probability that the birthdays of five persons chosen at random will fall in twelve different calender months is zero. You would need at least twelve persons to have a non zero probability.
What experimental term is it called when a ruler is dropped to the floor?
The experimental term is "free fall experiment." This is used to study the acceleration due to gravity by measuring the time it takes for an object, such as a ruler, to fall freely from a certain height.
What is the probability of getting less than 10 when you roll a dice?
A die normally has six sides with the numbers 1 to 6 on them, so any roll will be less than 10 and thus the probability of getting less than 10 with a die is 1. With two normal dice, the sum of the digits on the dice added together ranges from 2 to 12 and the probability of getting less than 10 is the same as 1 minus the probability of getting 10 or more. There are 36 ways the two dice can fall and 10 can be achieved in 3 ways (4&6, 5&5, 6&4), 11 can be achieved in 2 ways (5&6, 6&5) and 12 in 1 way (6&6). Thus the probability of getting 10 or more with 2 dice is (3+2+1)/36 = 6/36 = 1/6 So the probability of getting less than 10 is 1-1/6 = 5/6
What is the probability pie day will fall on a Saturday or Sunday?
Approx 2/7.
What is probability that your birthday will fall on Saturday in any given year?
1/7
What is probability that your birthday will fall on Sunday this year?
one in seven7 days a week
What causes an object to fall from a height?
Gravity causes an object to fall from a height. Without gravity, the object would just be floating in the air.
