A purchaser of electric relays buys from two suppliers, A and B. Supplier A supplies two of every three relays used by the company. If 60 relays are selected at random from those in use by the company, find the probability that at most 39 of these relays come from supplier A. Assume that the company uses a large number of relays. (Use the normal approximation. Round your answer to four decimal places.)

Our required probability is 0.3162.

Step-by-step explanation:

Since we have given that

n = 60

Probability of success =

Probability that at most 39 of these relays come from supplier A would be

Hence, our required probability is 0.3162.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
