Hiro has a stack of cards with one number from the set 1, 1, 2, 2, 3, 3, 3, 4 written on each card. What is the probability that he pulls out a 3 first and then pulls out a 2 without replacing them?

Answers

Answer:

3/28

Step-by-step explanation:

Given in the question that,

stack of cards have numbers (1, 1, 2, 2, 3, 3, 3, 4)

Total number of cards = 8

Number of card with 3 on them = 3

Number of card with 2 on them = 2

To find the probability that he pulls out a 3 first and then pulls out a 2, we will multiple the probability of having 3 with 2.

Probability of having 3 = 3/8

Probability of having 2 = 2/7 (without replacing)

3/8 x 2/7 = 3/28

Thus, the answer is 3/28

Answer:3/28

Mike jogged 6 laps around a 0.25-mile track on Mondat and 7 laps on Tuesday. How many miles did he jog on Monday and Tuesday combined?

Answers

Given:
Monday: 6 laps around a 0.25-mile track
Tuesday: 7 laps around a 0.25-mile track

Total miles jogged on both days.

0.25(6 + 7) = 0.25(13) = 3.25 miles

Mike jogged a total of 3.25 miles on Monday and Tuesday combined.

All you have to do is add up the number of laps and multiply that by the distance for each lap so its (6 +7)*0.25.

6+7=13
13*0.25= 3.25 miles
ANSWER= 3.25 miles

ashton is saving money to buy a new bike.he needs $120 but has only saved 60% so far how much money does ashton need to buy the scooter?

Answers

Answer:

Ashton needs $48 to buy the bike

Step-by-step explanation:

The cost of the bike is $120. In this moment Ashton has saved 60 % to convert it to money we have to multiply the cost of the bike and the percentage saved and divide it by 100 % to eliminate the percentage units.

$(120 * 60)/(100)= 72$
