Question

9. A bag contains 13 blue blocks

and 17 red blocks. Below shows
how many times each block was
pulled then replaced. What was the
experimental probability of choosing
a red block?
Red
Blue
22

Answer 1

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

Now

Empirical probability of choosing a red block, P(e) = n(E) / n(S)

= 17/30

= 0.566
