a. Explanation Given info: In Online Shopping Survey, there are 427 different adult women in which 162 women chose the online clothes. Calculation: Exact probability : For the exact probabilities that is, the event of selecting women chose the category of clothing online and the selections are made without replacement, are taken as not independent. Then the event of ‘getting women chose the category of clothing online in second selection’ is affected by another event ‘getting women chose the category of clothing online’. The required probability is, P ( Both women chose online clothes ) = P ( First woman chose online clothes and b. To determine To find: The probability of randomly selecting 10 surveyed women did not choose the category of clothing, when selections are made without replacement.
