What is the probability of getting 2 heads when you toss three coins?
If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2, the probability is 3/8, or 37.5%. There are 3 independent coin tosses, each of which is equally likely to come up heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH, etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2 heads, so the probability of that is 3/8.
What is the total number of integers between 100 and 300 that are divisible by 3?
The total number of integers between 100 and 300 that are divisible by three is 66.
Why is a probability less than or equal to 1?
Let's take the simple case of tossing a coin. You may end up with the Head facing up or the Tail facing up. If the coin is perfectly balanced then in the long run (say a 1000 tosses) you will get about 500 heads and 500 tails. You will never get 1000 heads or 1000 tails. In this simple experiment the probability of heads is defined as 500/1000 and the proability of tails is defined as 500/1000 where the numerator represnets in each case a "tagged" event and the denominator denotes the "toal" events. Thus in the case above the occurrence of Head or Tail can never be 1000, it will always be less the 1000 (the total attempts in the experiment). Hence 500/1000 (ratio of "tagged" event to the total eveents) which is defined as the probability can never be 1. In the extreme case where the coin is weighted (a counterfeit)such that you always get heads facing up then out of 1000 tries you will get 1000 heads and zero tails. In this case the probability of heads is 1 and the probability of tails is zero. I hope this explanation helps. Thus true probablity of an event lies between 0 and 1, both inclusive.
How many possible outcomes of tossing a coin 10 times have at least 2 heads?
There are 210 total possible outcomes from flipping a coin 10 times.There is one possible outcome where there are 0 heads.There are 10 possible outcomes where there is 1 head.So there are 210 - 11 possible outcomes with at least 2 heads.(1013)
If you flipped a coin ten times what is the probability you would get five heads?
We need to calculate two things:How many possible possible series of 10 coin flips are there? As we flip 10 times and each time we can have either heads or tails we have 2 by the power of ten possibilities, or a total of 1024 unique possible series.Now, how many of those series have exactly five heads and five tails? Lets assume we have ten "pre filipped" coins at hand - 5 tails and 5 heads. How many possible combinations are there. Well, if they were all different, you would have 10! (10 factorial = 10*9*8*7*6*5*4*3*2*1) possibilities.How ever, the 5 heads are identical and so are the 5 tails, so if I interchange the locations of two coins that are both heads for example I still get the exact same series. There are 5! possible heads combinations, and 5! tails combinations.Thus, the total number of unique combinations is 10!/(5!*5!) which happens to be 252.So, out of 1024 possible series, 252 contain exactly 5 heads.The probability thus is 252/1024=0.24609375 (roughly 25%)

In collection of animals including birds and beasts they had 43 heads and 120 feets. How many birds and beasts are there in collection?
Birds and beasts have one head each. So totally there are 43 birds & beasts. Let number of birds = x number of beasts = (43-x) Birds have 2 feet and beasts have 4 feet. Total feet = 2 * no of birds + 4 * no of beasts = 2 * x + 4 * (43 -x) = 172 - 2*x (on simplification) = 120 (given) 172 - 2*x = 120 2*x = 172 - 120 = 52 x = 52/2 = 26 number of birds = x = 26 number of beasts = 43 -x = 43 -26 = 17 (check: 26 + 17 = 43 ; 26*2 + 17*4 = 52 + 68 = 120)
