In a group of 90 students, 65 watch rugby, 71 play a sport and 15 do neither. Find the probability that a student chosen at random from those who play a sport
does not watch rugby.

probability of selecting a student who plays a sport but does not watch rugby out of the people who play a sport.

Step-by-step explanation:

"Find the probability that a student chosen at random from those who play a sport  does not watch rugby."

90-15= 75 students either play a sport OR watch rugby

65+71-75=

136-75=

61 people play a sport AND watches rugby

14 people play a sport and DOES NOT watch rugby

is the probability of selecting a student who plays a sport but does not watch rugby out of the people who play a sport.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
