Calculating the Probability of Winning in a Lottery

To calculate the probability of winning in a lottery, we need to determine the number of favorable outcomes (winning tickets) and the total number of possible outcomes (total number of tickets).

In this case, we have a lottery with 50 tickets, out of which 8 are winning tickets. We want to find the probability of randomly selecting 4 winning tickets.

To calculate the probability, we can use the formula:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Let's calculate the probability step by step:

1. Determine the number of favorable outcomes (winning tickets): - In this case, we have 8 winning tickets.

2. Determine the total number of possible outcomes (total number of tickets): - In this case, we have 50 tickets.

3. Calculate the probability: - Probability = (Number of favorable outcomes) / (Total number of possible outcomes) - Probability = 8 / 50

Therefore, the probability of randomly selecting 4 winning tickets from a lottery with 50 tickets, where 8 are winning tickets, is 8/50.

Please note that this calculation assumes that each ticket has an equal chance of being selected and that the tickets are drawn without replacement (meaning once a ticket is selected, it is not put back into the pool for the next selection).
