Answer: 3/10
Explanation:
From the question, we are informed that Kieran picks a bead out of a bag without looking and that he records the colour and replaces the bead.
He does this 50 times and he picks out a red bead 15 times. The probability of picking a red bead will be the number of times a red bead was picked divided by the number of title times a bead was picked. This will be:
= 15/50
= 3/10
