Question

1. Find the mean of the first five whole numbers

2. A coin is tossed. What is the probability of getting head?​

Answer 1

Answer:

1. As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.
2. The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

Answer 2

Answer:

1. the mean if first five while numbers is 2

2.the probability of getting head is 1/2or 0.5
