the Venn diagram shows the number of people in a group of friends who have brown hair and green eyes

9514 1404 393

  1.  a. 1/4

  2.  c. 1/3

Step-by-step explanation:

1. P(g | b) = P(g&b)/P(b) = (1/11)/(4/11) = 1/4

__

2. P(b | g) = P(g&b)/P(g) = (1/11)/(3/11) = 1/3

Comment on the solutions

Here, we have used the probabilities, which required that we determine the total number of people as well as the number in each circle. One could just as easily use only the numbers in the relevant circle.

1. of the 4 folks with brown hair, 1 has green eyes, so 1/4 is the probability of green eyes, given brown hair.

2. of the 3 folks with green eyes, 1 has brown hair, so 1/3 is the probability of brown hair, given green eyes.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
