Answer #1

Answer:

Given that:

Suppose 4 people are chosen at random from a group of 1200.

Excellent 8% Good 42% Fair 36% Poor 13% Other 1%

Number of people with excellent shape responses = 1200 +0.08 = 6

Hence,

Probability that all four would rate their financial shape as excellent

= (96/1200) * (95/1199) * (94/1198) * (93/1197)

= 0,08 0,08 * 0,08 * 0,08

= 0.00004096

= 0.000041
