If p(a or b)equals=0.60.6, p(a)equals=0.40.4, and p(a and b)equals=0.350.35, find p(b).

P(B) = 0.55 .

Step-by-step explanation:

We are given that  P(A or ​B) = 0.6 ​, P(A) = 0.4 ​, and​ P(A and ​B) = 0.35 .

As we know that;

     P(A or B) = P(A) + P(B) - P(A and B)

         0.6 = 0.4 + P(B) - 0.35

           P(B) = 0.35 + 0.6 - 0.4 = 0.55

Therefore, P(B) = 0.55 .

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
