Question

Suppose that the probability a seed will germinate is 85%. What is the probability that 7 of these seeds will germinate when 10 are planted?
a.0.1298
b.0.385
c.0.12
d.0.141

Answer 1

total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1  = 120
probability of each outcoe is 0.85^7* (0.15)^(3)  = 0.0010819

Required probability = 120 * 0.0010819 =  0.1298
