There are 15 lottery tickets available. Roy knows that 6 of them are winning. If Roy picks one ticket at random, what is the probability that it will be a winning ticket?

Question

BenicioBrody · Answer

The probability that Roy will pick a winning lottery ticket is 2/5 or 40%, calculated by dividing the number of winning tickets (6) by the total number of tickets (15). 
 To find the probability that Roy picks a winning ticket from the 15 available tickets, we use the formula for probability which is the number of favorable outcomes divided by the total number of outcomes. In this case, the number of winning tickets (favorable outcomes) is 6, and the total number of tickets (total outcomes) is 15. 
 Therefore, the probability of Roy picking a winning ticket is: 
 Probability = Number of winning tickets / Total number of tickets = 6/15 = 2/5. 
 The probability that Roy will pick a winning ticket is 2/5, or 40%, when a ticket is selected at random.
