Given P(A) = 0.3, P(B) 0.63 and P(BA) = 0.79, find the value of P(A and B), rounding to the nearest thousandth, if necessary.

P(A and B) = 0.14.

Step-by-step explanation:

Venn probabilities:

Suppose we have two events, A and B. The probability P(A and B) is given by:

In which is P(A or B).

In this question:

P(A) = 0.3, P(B) = 0.63, P(A or B) = 0.79. So

So

P(A and B) = 0.14.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
