Step-by-step explanation:
Total times the boxes were pulled and replaced = 22 + 8 = 30
Now
no of favourable cases, n (E) = 17
no of sample space, n(s) = 30
Empirical probability of choosing a red block, P(e) = n(E) / n(S)
= 17/30
= 0.566
there are 2 blue marbles, 8 red marbles, and 8 plastic red marbles
there are 18 marbles in total
8/18
Answer:
$55
its $150 - $40 = $110
$110 / 2 = $55
n=6
(n-18)/3 = -4
multiply by 3
n-18 = -12
add 18
n = 6
