Question

johnny has a coin that is three times more likely to land on heads than tails. i. how many heads should johnny expect to see after 4 coin flips?

Answer 1

Johnny should expect to see 3 heads after 4 coin flips.

Step-by-step explanation:

The probability of landing on heads with Johnny's coin is 3 times more likely than landing on tails. Since the probability of landing on tails is 1/4, the probability of landing on heads is 3 times that, which is 3/4. To calculate the expected number of heads after 4 coin flips, we can multiply the probability of getting heads on each flip by the total number of flips. Therefore, Johnny should expect to see 3 heads after 4 coin flips.

Answer 2

After 4 coin flips, Johnny should expect to see 3 heads and 1 tails

Step-by-step explanation:

If the coin is 3 times more likely to land on heads than tails, then that means the probability ratio of the coin landing heads to tails is 3 to 1, or 3:1. This means that if a coin is flipped for times, it is statistically probable for the coin to land on heads 3 times, and tails just 1 time. This can be scaled too. If a coin is flipped 8 times, it is probable that the coin will land on heads 6 times, and tails 2 times.
