Karla tosses a penny 20 times. How many times is the penny most likely to land on heads
10
Yeah, 10.
10
To determine how many times the penny is most likely to land on heads, we need to consider that a penny has two sides - heads and tails. When tossed in the air, assuming both sides are equally likely to appear, the probability of landing on heads is 1/2 or 0.5.
To find the most likely number of heads in 20 tosses, we can use the concept of expected value. The expected value is obtained by multiplying the number of trials by the probability of success in a single trial.
So, for each toss, the expected value of landing on heads is 20 tosses x 0.5 probability = 10.
Therefore, in 20 tosses, the penny is most likely to land on heads 10 times.
