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
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
