1. The NGA hoped to raise more than $3000 for cancer. Every time a student donated $40
they would get to pie a math teacher in the face. How many donations would it take for
the students to reach or exceed their goal?

if they are donating by 40 only then 75 donations

Step-by-step explanation: hope this helps if wrong plz tell me if right plz consider giving brainliest

Step-by-step explanation:

Given ;

a) P ( X = 13 ) = C(15,13) x 0.56^13 x (1-0.56)^2 = 0.0108

b) Mean = np = 15 x 0.56= 8.400

Standard deviation = √(np(1-p)) = √(15 x 0.56 x (1-0.56)) = 1.9225

c) P(X>10) = 1 - P(X≤10) = 1 - 0.8633 = 0.1367

d) P(X≥12) = P(X=12) + P(X=13) + P(X=14) + P(X=15) = 0.0498

e) P(Y=3) = C(3,1) x 0.56^1 x (1-0.56)^2 x 0.56 = 0.1821

f) P(Y=2) = C(2,1) 0.56^1 x (1-0.56)^1 x 0.56 = 0.2760
