The Probability that one bulb is red and one is yellow?

27 Bulbs contains 11 red, 9 yellow and 7 purple

Verified Answer :

I have a solution here where:

A bag of 27 Tulip bulbs contain 10 red tulip bulbs, 8 Yellow, and 9 purple tulip bulbs. 

Red- 
10/27= .37 
times 100 gives percentage 
=37% 

Yellow- 
8/27= .3 
times 100 gives percentage 
30%

Answer:

\(\frac{11}{39}\)

Step-by-step explanation:

Given,

The number red bulb = 11,

Yellow bulb = 9,

Purple = 7,

Total bulbs = 11 + 9 + 7 = 27,

If two bulbs are taken,

Then, the probability that one bulb is red and one is yellow

\(=\frac{^{11}C_1\times ^9C_1}{{27}^C_2}\)

\(=\frac{11\times 9}{\frac{27!}{2!\times 25!}}\)

\(=\frac{99}{\frac{27\times 26}{2}}\)

\(=\frac{99}{27\times 13}\)

\(=\frac{11}{39}\)
