The probability that an event will occur plus the probability that it will not occur equals 1.
What is the formula in probability?
Probability equals favorable outcomes divided by total number of outcomes.
What is the probability of a sample mean being less than 12752 or greater than 12755?
sample n equals 37 sorry and if you could write the equation that would be helpful
An area of a normal probability distribution represents?
The number 1. The area of any probability distribution equals 1.
What is the probability of randomly selecting a score from a normal distribution with a value greater than z equals -2?
Pr(Z > -2) = 97.725%
What is the probability of randomly selecting one orange triangles and then one red triangle if you have 8 green 8 red 7 blue 5 orange 7 yellow 5 purple assume the the first one is replaced?
The probability is orange / total * red / total, which equals one fortieth. 5/40*8/40 = 40/1600 = 1/40

Impossible
For lamda equals 5.5 the probability of x equals 2 is?
The answer depends on what the distribution is!
What is the probability that it is an ace or a heart in a 52-deck of cards?
If you add 1 for the ace to 13 for Hearts cards you have 14 cards out of a 52 card pack. So the probability of selecting one of those 14 cards is 14/52 = 7/26 That is 0.2692307692307.........( recurring 69230) Correcting to 4 significant figures that equals 0.2692 which equals 26.92% That means that you will select a correct card in just over 1 in 4 times.
