About 30% of adult Internet users are between 18 and 29 years of age. Suppose the probability that a randomly chosen Internet user is in this age group is exactly 0.3. If 15 users are selected at random. (Use the tables or your calculator to analyze a Binomial probability distribution with probability of success of 0.3 and number of trials of 15). What is the probability that at most 10 are between 18 and 29 years?

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
