Answer:
0.4545 or 45%
Step-by-step explanation:
Do-Gooders toys for boys = 5
Southside toys for boys = 6
Given that the first toy pulled out of the bin is a toy for boys, to find the probability that this toy was donated by the Do-Gooders, the number of toys for girls donate shouldn't be considered since there's a zero-chance that the toy in question is for girls. Therefore:
[tex]Total\ sample \ space = 5+6 =11\\P(Do-Gooders)=\frac{5}{11} =0.4545[/tex]
There's a 0.4545 or 45% probability that it was donated by the Do-Gooders.
