The average of 5 numbers is 20. what is the sum of these same numbers?

Vinil7 [7]

Average = (A₁+A₂+A₃+A₄+A₅)/5. Since average = 20 (GIVEN), then:

20 = (A₁+A₂+A₃+A₄+A₅)/5

Or (A₁+A₂+A₃+A₄+A₅) = 20x5

(A₁+A₂+A₃+A₄+A₅) = 100

Three shooters shoot at the same target, each of them shoots just once.The first one hits the target with a probability of 50%,

nekit [7.7K]

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
