Answer:
Mean=50
Step-by-step explanation:
The mean of a probability distribution is a <u>measure of central tendency</u>,and gives information about how the possible values of x are distributed.
The vertical axis measures the probability of finding a specific value of x in the sample. The probability of finding a value near the mean is high (that is why the value of the function that is depicted in the vertical axis, increases as we get closer to the mean=50): this is because the mean is that value of x around which higher probability of occurrence is associated.
