Rodney packs 4 shirts for a trip at random. The closet contains 10 shirts: 5 striped, 3 plaid, 2 solid colored ones. What is the
Travka [436]

Answer:

1 / 7

Step-by-step explanation:

Given :

Number of shirts in closet = 10

Number of striped shirt = 5

Number of plaid = 3

Probability of choosing 2 plaid shirts and 2 stripped shirt

Probability = required outcome / Total possible outcomes

Total possible outcomes = 10C4

Required outcome :

2 plaid shirt from 3 = 3C2

2 stripped shirts from 5 = 5C2

Hence,

P(choosing 2 plaid and 2 stripped shirt) :

(3C2 * 5C2) / 10C4

Recall:

nCr = n! / (n-r)!r!

Using calculator :

(3C2 * 5C2) / 10C4

= (3 * 10) / 210

= 30 / 210

= 1 / 7

scoray [572]

Emily's figurine is 17 inches taller than Chen's figurine

Step-by-step explanation:

Emily and Chen built clay figurines for art class

  • Emily figurine is 5' 1" tall
  • Chen's figurine is 3' 8" tall

We need to find how much taller is Emily's figurine than Chen's in inches

To solve this problem we must to change the heights of the two figurines to inch

∵ Emily's figurine is 5' 1" tall ⇒ 5 feet and 1 inch

∵ 1 foot = 12 inches

∴ The height of Emily's figurine = 5(12) + 1

∴ The height of Emily's figurine = 60 + 1

∴ The height of Emily's figurine = 61 inches

∵ Chen's figurine is 3' 8" tall ⇒ 3 feet and 8 inches

∵ 1 foot = 12 inches

∴ The height of Chen's figurine = 3(12) + 8

∴ The height of Chen's figurine = 36 + 8

∴ The height of Chen's figurine = 44 inches

To find how much taller is Emily's figurine than Chen's in inches subtract their heights

∵ The difference between the two figurine = 61 - 44

∴ The difference between the two figurine = 17 inches

∴ Emily's figurine is 17 inches taller than Chen's figurine

Emily's figurine is 17 inches taller than Chen's figurine
