There are 2^3 possible combinations
So
P (getting no tails) = 1/2 * 1/2 * 1/2 = 1/8 as each time there is 1/2 chances of getting a heads
B: Negative 9 and 3 over 6
Answer: 14.1%
Step-by-step explanation:
Number of T-shirts shipped = 2800
Number of T-shirts that have a defect = 396
Therefore, the experimental probability that a T-shirt has a defect will be:
= Defect T-shirts / Total T-shirts × 100
= 396 / 2800 × 100
= 14.1%
I don't know the answer but A is definitely not the answer just to save you a chance
