Question

Given that events a and b are independent and that p(a) = 0.8 and p(b|a) = 0.4, then p(a and
b.= 0.32.
a. True
b. False

Answer 1

p(a) = 0.8
p(b|a) = 0.4 i.e (probability of b after event a has happened)
p(a n b) ≠ 0.32
false
cause the equation asks for mutually exclusive events nd not the inclusive event prob for b
