The probability that an archer hits the target when it is windy is 0.4; when it is not windy, her probability of hitting the tar

stiks02 [169]

Answer:

x = 6

Step-by-step explanation:

The probability that this archer hits her first shot is given by t the probability of being windy and that she hits the shot added to the probability of not being windy and that she hits the shot:

$P(H_{first}) = P(H_w)*P(W)+P(H_{nw})*(1-P(W))\\P(H_{first})=0.4*0.3+0.7*(1-0.3)\\P(H_{first})=0.12+0.49 = 0.61$

If the probability that she hits the target on her first shot is 0.x1, the value of x is:

$P(H_{first})=0.61=0.x1\\x=6$
