When ryan is serving at a restaurant, there is a 0. 75 probability that each party will order drinks with their meal. during one hour, ryan served 6 parties. assuming bc that each party is equally likely to order drinks, what is the probability that at least one party will not order drinks?

0.82

Step-by-step explanation:

We are given that

Total number of parties=n=6

The probability that each party will order drinks with their meal,q=0.75

The probability that party will not order drink with their meal=p=1-0.75=0.25

We have to find the probability that at least one party will not order drinks with their meal

Binomial probability distribution

Using  the formula

Using formula;

Hence, the probability that at least one party will not order drinks=0.82

99

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
