Answer:
$16.80
Step-by-step explanation:
Since the shirts are marked down by 30%, you need to multiply the cost of the shirt by the percentage.
$24 × 0.3 = $7.20
Next, subtract the discount from the original price to find the discounted price.
$24 - $7.20 = $16.80
2²=4 2×2
3²=9 3×3
4²=16 4×4
5²=25 5×5
6²=36 6×6
7²=49 7×7
8²=64 8×8
9²=81 9×9
10²=100 10×10
11²=121 11×11
Ummm i don't know what the pmf would be but the probability of grabbing a blue sock would be 10 out of 100...
