Aand b are two events.

p(a)=0.25 , p(b)=0.5 and p(a and b)=0.15 .

what is the value of p(a or b) ?

0.15

0.25

0.60

0.90

The value of P(A or B) =0.60

Step-by-step explanation:

Given: A and B are two events.

P(A)=0.25 , P(B)=0.5 and P(A and B)=0.15

We know that the value of P(A or B) is given by the formula :

Hence, the value of P(A or B) =0.60

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
