One morning a bagel shop sold 3 plain bagels, 6 raisin bagels, and 6 sesame seed bagels. if the shop sells 20 bagels the next morning, predict how many of the bagels will be plain.

The predicted number of plain bagels that will  be sold next morning is:

                                              4

One morning a bagel shop sold 3 plain bagels, 6 raisin bagels, and 6 sesame seed bagels.

This means that the total numbers of bagels that were sold are: 3+6+6=15 bagels.

Hence, the Probability of the plain bagels sold are:

i.e. P(plain bagels)=3/15=1/5

( Since, the probability is the ratio of the number of favorable outcomes to the total number of outcomes .

Number of plain bagels=3

and Total number of bagels= 15 )

If the shop sells 20 bagels the next morning.

Then the predicted number of the bagels will be plain are:

P(plain bagels)×20

=  (1/5)×20

=  4  plain bagels

Hence, the answer is: 4

you cant really predict how many bagels will be sold the next morning because of different scenarios but mathematically speaking if you compare plain bagels to total bagels you get 3/15 so if you multiply the denominator by 1 1/4 to get twenty as the denominator then you have to do the same to the numerator to get a fraction of 3.75/20 or roughly 3-4 plain bagels sold
