In other words, if the number of successes and failures in the sample is large enough, then we can assume that the distribution of the count of successes follows a normal distribution.

Our sample size here n is equal to 125 and our population proportion of the proportion of children that are reached each week by radio is 88% so p is 0.88. So now let's calculate np so n is 125 times p is 0.88 and is this going to be greater than or equal to 10.
