Acheese can be classified as either raw dash milk or pasteurized. suppose that 91% of cheeses are classified as pasteurized. (a) two cheeses are chosen at random. what is the probability that both cheeses are pasteurized? (b) six cheeses are chosen at random. what is the probability that all six cheeses are pasteurized? (c) what is the probability that at least one of six randomly selected cheeses is raw dash milk? would it be unusual that at least one of six randomly selected cheeses is raw dash milk?

Step-by-step explanation:

Given that a cheese can be classified as either raw dash milk or pasteurized. Suppose that 91% of cheeses are classified as pasteurized.

Each cheese is independent of the other and there are only two outcomes.

Hence X = no of cheeses pasteurized is binomial (2,0.91)

a) P(x=2 ) when n=2  is

b) n=6.  

P(x=6) =

c) P(atleast one raw dash milk) = 1-P(all pasteurised)

=0.8281

Since probability is 0.83 it is not unusual.

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
