Question

A jar of gumballs contains 4 reds, 2 greens, and 6 blues. What is the probability of getting two blues in a row without replacement?

Answer 1

Answer:
`\bold{(5)/(22)}`

Explanation:

Red = 4, Green = 2, Blue = 6 ⇒ Total = 12

`\text{Probability =}(\#\ of\ blues)/(total)*(\# \ of\ blues\ remaining)/(total\ remaining)\\\\.\qquad \qquad \quad =(6)/(12)* (5)/(11)\\\\.\qquad \qquad \quad =(1)/(2)* (5)/(11)\\\\.\qquad \qquad \quad =(5)/(22)\\`
