Answer:
the probability of the student chose running is 26 ÷ 63
Step-by-step explanation:
The computation of the probability of the student chose running is shown below:
= (Total students - football selected - tennis selected) ÷ (Total students)
= (63 - 20 - 17) ÷ 63
= 26 ÷ 63
Hence, the probability of the student chose running is 26 ÷ 63
B. 7y - 15
10y - 3(y+5)
= 10y -3y - 15
= 7y -15
16 minutes
multiply 20 by 80% (20 times .80)
