Suppose pr(a)=0.25 and pr(b)=0.48, where a and b are mutually exclusive. find pr(a ? b).
pr(a ? b)=
(simplify your answer. type an integer or a decimal.)

 The required value is P(A ∪ B) = 0.73.

Step-by-step explanation:  Given that A and B are two mutually exclusive events where

We are to find the following probability :

P(A ∪ B).

We know that

the intersection of two mutually exclusive events is null event. That is,

A ∩ B = ∅     ⇒  P(A ∩ B) = 0.

From the laws of probability, we have

Thus, the required value is P(A ∪ B) = 0.73.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
