X-y=3
x+y=13

Add the two equations to get the following in order to solve for x:
2x=16
x=8

Next you substitute into x+y=13 to solve for y

8+y=13
y=5

Therefore, x=8 and y=5

DIA [1.3K]

Answer:

P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B  ⇒ 97 Female.

Total Male = 65 type A, 38 type B   ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = \frac{number of male in B}{total number of male}

                           = \frac{38}{103}

                           = 0.368

P(Male or Type B) = \frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}

                              =  \frac{103 + (50 - 38)}{200}

                              = \frac{103 + 12}{200}

                              = \frac{115}{200}

                              = 0.575

 Hence, P(Male or Type B) > P(Male | Type B)
