plsssss do ans fast bec i hav exam 2morow

if A and B are the only two outcomes of an event and P(A} =0.32 then value of P (B) would be.......

a. 0.38

b.0.68

c. 0.78

d. 0.38

(b) 0.68 because the sum of the probability of total outcomes in a random experiment is 1

Since P(A)= 0.32

Therefore, P(B) = 1-0.32

  = 0.68

  • 5

(b) 0.68

because the highest no. is 1 

therefore, 1-0.32= 0.68

  • 3
