We now demonstrate the above results with a tree diagram. Example 4.5.3 4.5. 3. Suppose a jar contains 3 red and 4 white marbles. The individual probabilities of the outcome of a cross between pea plants that are heterozygous for one particular trait are given as follows: 1. The probability of the pea plant being tall is 3/4, and that it is short is 1/4. 2. The probability of the pea plant having a round seed is 3/4 and having a wrinkled seed is 1/4.

Find the probability. This problem requires us to find the probability that p1 is less than p 2. This is equivalent to finding the probability that p 1 - p 2 is less than zero. To find this probability, we need to transform the random variable (p 1 - p 2) into a z-score. That transformation appears below.

The general multiplication rule. For any two events, we can say that. P ( A and B) = P ( A) ⋅ P ( B | A) ‍. The vertical bar in P ( B A) ‍ means "given," so this could also be read as "the probability that B occurs given that A has occurred." Unit 1 Absolute value & piecewise functions.
