3. -125 points TEAFM2 5.4.026. My Tris Speaker has a lifetime batting average of 0.345. Assume that Tris getting at least three hits in a game? (Round your answer to six decimal places.) Speaker came to bat officialy four times every game played. What would be Tris Speaker's probability 40-125 points TEAFM2 5.4.036. An oil company estimates that only 1 well in 18 will yield commercial quantities of oil. Assume that successful drilled wells represent independent events. If 12 wells are drilled, find the probability of obtaining a commercially successful well for the following number of times.

Explanation / Answer

Question

Pr(Hit) = 0.345

n = 4

as distribution is binomial here

Pr(X >= 3) = BIN (X > = 3 ; 4 ; 0.345) = BIN (X = 3 ; 4 ; 0.345) + BIN(X = 4; 4 ; 0.345) = 0.121754

(4) Here probability of successful drilling a oil well = 1/18

If X is the number of successful drilled well

then

Pr(X = 1) = BIN(X = 1; 12; 1/18) = 0.355508
