Answer:
Let X be the number of times the target is hit. The probability P(X≥1) then equals 1 minus the probability of missing the target three times:
P(X≥1) = 1− (1−P(A)) (1−P(B)) (1−P(C))
= 1−0.4*0.3*0.2
= 0.976
To find the probability P(X≥2) of hitting the target at least twice, you can consider two cases: either two people hit the target and one does not, or all people hit the target. We find:
P(X≥2)=(0.4*0.7*0.8)+(0.6*0.3*0.8)+(0.6*0.7*0.2)+(0.6*0.7*0.8) = 0.788

Slope: The slope of a line is also called as gradient of line it is denoted by a letter m.
Probability that the first captain's first pick is a girl = 11/21
Probability that the first captain's second pick is a girl = 12/25
<span>the probability that the first captain will pick two girls before picking any boys = 11/21 x 12/25 = 132/525 = 44/175</span>
