On a track and field team, 8% of the members run only long-distance, 32% compete only in field events, and 12% are sprinters onl
kondor19780726 [428]

Answer:

0.40

Step-by-step explanation:

Members who run only  long distance = 8%

So, probability that a member will run only long distance = P(A) = 0.08

Members who compete only in field events = 32%

So, probability that a member will compete only in field events = P(B) 0.32

Members who are sprinters = 12%

So, probability that a member is sprinter = P(C) 0.12

We have to calculate the probability that a randomly chosen team member runs only long-distance or competes only in field events. i.e we have to find P(A or B). Since these events cannot occur at the same time, we can write:

P(A or B) = P(A) + P(B)

Using the values, we get:

P(A or B) = 0.08 + 0.32 = 0.40

Thus, the probability that a randomly chosen team member runs only long-distance or competes only in field events is 0.40

I need this answer please
julsineya [31]

Answer:

3a+6b = 45

Multiply by 2

6a +12b = 90.....(1)

2a- 2b = -12

Multiply by 3

6a - 6b = -36 .....(2)

(1)-(2)

18b = 126

b= 7

3a+6b = 45

3a + 6(7) = 45

3a +42 = 45

3a = 3

a= 1

(a,b) = ( 1,7)
