Question

If six pieces come off of a hot press, find the probability that two are Grade A, three are Grade B, and one is a Cull.

Answer 1

Explanation:

Given data:

No of pieces = 6

Grade A = 2

Grade B = 3

Cull = 1.

Solution:

Probability that two are Grade A

P = 2/6

= 0.33

Probability that 3 are Grade B

P = 3/6

= 0.5

Probability that 1 is a cull

P = 1/6

= 0.17
