Answer:
13/50
Step-by-step explanation:
First, we need to put all the possible scenarios.
Let's call coin A as the coin that flips head 40% of the time, and coin B the 60% of the time.
Now, 40% in fraction is 40/100 = 4/10 = 2/5 for coin A. This is the probability of the coin A to get head. (Pa)
60% of the time is 60/100 = 6/10 = 3/5. Probability to get head in coin B (Pb)
Now, we don't know which coin is picked, all we know is that the first flipping is head. so, as the coins are picked randomly, we have 1/2 probability to choose either coin A or coin B, so, let's suppose we picked coin A:
Pa = 1/2 * 2/5 = 2/10 * 2/5 = 4/50
If the coin picked is coin B:
Pb = 1/2 * 3/5 = 3/10 * 3/5 = 9/50
So, finally the probability that if we flip the coin a second time, to get a head, no matter which coin was picked, is just the sum of both probabilities so:
P = 4/50 + 9/50 = 13/50
The probability it will be heads on the next flip is 0.24.
How to calculate probability?
From the information given, a bag comes up heads 40% of the time, and the other will come up heads 60%.
The probability it will be heads on the next flip will be:
= 40% × 60%
= 0.4 × 0.6
= 0.24
