A fair die is rolled 5 times. What is the probability that a 3 is obtained on at least one of the rolls? Round your answer to th
Lerok [7]

Answer:

0.200

Step-by-step explanation:

The probability of obtaining a 3, in one roll of a fair die is 1/6.

Now, we have 5 rolls.

We now want to know the probability of a 3 showing up in at least one of the rolls.

This simply mean, we add the probabilities of three showing one time plus probability of three showing in 2 of the rolls e.t.c

This means we can have 3 showing up to 5 times.

We add the probabilities as follows:

(1/6) + (1/6)^2 + (1/6)^3 + (1/6)^4 + (1/6)^5 = 0.199974 = 0.200

Torri had $20 to buy a birthday present for her dad.She decided to buy a DVD for $18.The sales tax is 7%.Does she have enough mo
Brut [27]
Yes, Torri does have enough.
How to find the answer:
Find the decimal of 7% which is 0.07
Multiply 0.07 times $18 which gives you 1.26
 0.07 x 18 = 1.26
Add 1.26 to 18 which gives us 19.26
1.26 + 18 = 19.26
Our finale answer is 19.26
Torri has enough money to buy her dad the DVD.
Hope this helps! =)

Cross multiply for 2

Put 4x-5=3x-10 and subtract 3 on both sides. After that add 10 to both sides for 3

Divide everything by 5 and multiply everything by -2 for 4
