Explanation / Answer

Parr 1)

P(All 12 are same)

Use Excel function

BINOM.DIST(12,12,0.81,FALSE) = 0.0798

Part 2)

P(10 are on time')

BINOM.DIST(12,12,0.81,FALSE) = 0.2897

Q9)

Part 1

P(4 fail)

Use excel function

BINOM.DIST(4,15,0.12,FALSE) = 0.0694

Part 2)

P(x<4)

BINOM.DIST(3,15,0.12,TRUE) = 0.9041

Q10)

Part 2)

P(x<=13)

BINOM.DIST(13,23,0.67,TRUE) = 0.1966
