Rajans school is having a raffle. The school sold raffle tickets with 3-digits. Each digit is either 1,2,or 3. The school also s
belka [17]

Answer:

Step-by-step explanation:

We are told the school sold raffle tickets, and each ticket has a digit either 1, 2, or 3. The school also sold 2 tickets with the number 000.

Therefore we have the following raffle tickets:

123

132

213

231

312

321

000

000

From the given information, we can deduce that the school sold 8 tickets and only one ticket can contain the number arrangement of 123, but 000 appeared twice.

Probability of 123 to be picked=

1/8 => 0.125

Probability of 000 to be picked=

2/8 => 0.25

Since the probability of 000 to be picked is greater than 123, a ticket number of 000 is more likely to be picked

Alex787 [66]
