Question

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.

Answer 1

Answer:

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

                                              4

Step-by-step explanation:

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

Answer 2

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
