A box contains 22 widgets 4 of which are defective. If 4 are sold at random find the probability that a all are defective b none are defective

Probability that all 4 are defective is

0.181818181 and the probability that none of them us defective is 0.818181818

Step-by-step explanation:

The question Here says that A box contains 22 widgets 4 of which are defective. If 4 are sold at random find the probability that a all are defective b none are defective

The probability of all 4 widgets sold being defective is 4/22 = 0.181818181

And the probability of all 4 being effective will be

1 - (4/22)

= 9/11 or 0.818181818

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
