The $50 off was like a coupon after you brought all your merchanduse to the counter, so we have to add it back in to determine the number of shirts.
$400+$50=$450 original price of shirts
Original price ÷ price per shirt= quantity purchased
$450 ÷ $15/shirt= 30 shirts purchased
Allison bought 30 shirts.
Hope this helps! :)
The answer is (7/1/4)✖️(7/1/4)✖️(7/1/4)
I think
P would then =6.64 by my calculations
Answer:
0.3446
Step-by-step explanation:
P(X≥2) = 1 − P(X<2)
P(X≥2) = 1 − P(X=0) − P(X=1)
P(X≥2) = 1 − ₆C₀ (0.2)⁰ (0.8)⁶ − ₆C₁ (0.2)¹ (0.8)⁵
P(X≥2) = 1 − 0.2621 − 0.3932
P(X≥2) = 0.3446
