PLS HELP ME ASAP About 75% of the girls in grade 7 at Grande Rock Middle School prefer colored jeans to the regular blue ones. The randomly generated numbers in the table simulate this situation. The letter C represents colored jeans, and B represents blue jeans.

CCCBC BBCCC CCBBC CCBBC
CCCCC CCCCC BCCCC CBCCC
CCCCB CCCCC BBCCC CCCBB
CCCCC CBCCC BCCBC CCCBB
BCCCC CCCCB CCCBC CCBCC

Based on the data, the estimated probability that exactly four out of five girls prefer colored jeans is

Respuesta :

Hello!

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!

Answer:

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:

  CCCBC BBCCC  CCBBC   CCBBC

  CCCCC CCCCC   BCCCC    CBCCC

  CCCCB CCCCC   BBCCC    CCCBB

  CCCCC CBCCC    BCCBC    CCCBB

  BCCCC  CCCCB   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    BCCCC   CBCCC    CCCCB    CBCCC  BCCCC   CCCCB    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%
