It would be: 360- (101+133+76)
360-310 = 50 degree
bearing in mind, "t" is in years, 6months is just 1/2 year
solve for "r", you'd get a decimal amount, multiply times 100, to get the percentage form

Answer: 120
Step-by-step explanation:
From the question, we are informed that there are 10 people in a math club and that three people will be chosen for the Pi Day committee.
The number of different ways that the club members can structure the committee goes thus:
This can be solved by:
nCr = n! / r! (n - r)!
where n = 10
r = 3
= n! / r! (n - r)!
= 10! / 3! (10 - 3)!
= (10 × 9 × 8) / (3 × 2)
=120
