4 0

1/10 chance on winning with 1 ticket...so winning with 4 tickets =
1/10 * 1/10 * 1/10 * 1/10 = 1/(10^4) = 1/10,000

Answer:

1/10000

Step-by-step explanation:

Suppose you have a 1/10 chance of winning with a scratch-off lottery ticket.

If you buy 4 tickets

Probability of winning 1 ticket = 1/10

For 4 tickets we find the probability of every ticket

probability (winning first ticket)=1/10

probability (winning 2nd ticket)=1/10

probability (winning 3rd ticket)=1/10

probability (winning 4th ticket)=1/10

P(winning all 4) = $\frac{1}{10} *\frac{1}{10} *\frac{1}{10} *\frac{1}{10} = \frac{1}{10000}$
