Ответ:
To find this you do 5 * 0.75
0.75 represents the amount of girls that represent colored jeans
So the answer is 3.75
Hope this helps!

The estimated probability that exactly four out of five girls prefer colored jeans is : 0.45 or 45%
Step-by-step explanation:We are given a simulation as:
CCCBCBBCCC CCBBC CCBBC
B CBCCC
B BBCCC CCCBB
CBCCC BCCBC CCCBB
B B CCCBC CCBCC
where C represents colored jeans, and B represents blue jeans.
This means that the total number of outcomes is: 20
Now we are asked to find the estimated probability that exactly four out of five girls prefer colored jeans.
This means that we have to find the probability of simulation that have exactly 4 'C' in it.
Such outcomes are: CCCBC B CBCCC B CBCCC B B CCCBC CCBCC
Hence, total number of such outcomes=9
Hence, the estimated probability is:
9/20=0.45
Hence, probability is:
0.45 or 45%
