Answer:
40
Step-by-step explanation:
P (3) = number of 3's on a die/ total sides on a die
P(3) = 1/6
To get the number of times she gets a 3, multiply by probability by the number of total rolls
240*1/6 = 40
She should expect 40 rolls with a 3
Answer:
2x (2x^2 +x +1)
Step-by-step explanation:
f(x)-g(x)
9x^3 + 2x^2 -5x + 4 - (5x^3 -7x +4)
9x^3 + 2x^2 -5x + 4 - 5x^3 +7x -4
4x^3 +2x^2 +2x
2x (2x^2 +x +1)
