Billy has 2.4 m of ribbon for crafts. He wants to share it evenly with 12 friends. How many centimeters of ribbon would 7 friend

Dimas [21]

Answer: 34.29cm

Step-by-step explanation:

From the question, we are informed that Billy has 2.4 m of ribbon for crafts and that he wants to share it evenly with 12 friends.

The number of centimeters of ribbon that each of the 7 friends would get will be gotten by dividing 2.4m by 12. We can solve this by first converting 2.4meters to centimeters. This will be:

= 2.4meters = 2.4 × 100cm = 240 centimeters.

We then divide 240cm by 7. This will be:

= 240cm/7

= 34.29cm

Van guessed on all 8 questions of a multiple-choice quiz. Each question has 4 answer choices. What is the probability that he go

aleksandr82 [10.1K]

Answer:

0.267

Step-by-step explanation:

This can be solved using the binomial probability formula which is:

$P(success)=nCk*p^{k}(1-p)^{n-k}$

Where

n is total number of trials (here, the total number of questions is 8, so n = 8)

k is the number of attempts we are looking for (here, we want to find probability of 1 question correct, so k = 1)

p is the probability of success (here, success is getting a questions right. Since there are 4 choices and 1 is right, probability of right = 1/4)

Plugging all the info into the formula we get:

$P(success)=nCk*p^{k}(1-p)^{n-k}\\P(1QuestionRight)=8C1*(\frac{1}{4})^{1}(1-\frac{1}{4})^{8-1}\\P(1QuestionRight)=\frac{8!}{(8-1)!*1!}(\frac{1}{4})(\frac{3}{4})^7\\P(1QuestionRight)=\frac{8!}{7!*1!}(\frac{1}{4})(\frac{3}{4})^7\\P(1QuestionRight)=8(\frac{1}{4})(\frac{3}{4})^7\\=0.267$

Second choice is right.
