Question

Yasmin has a bag containing 165 colored beads. Her classmates take turns selecting one bead from

the bag without looking, recording the color in the table, and replacing the bead.

What is the experimental probability that a red bead is selected ?

Color Red Brown Orange Yellow
Number of Beads 10 15 17 13
P(Red)=__________

NOTE: List answer as a fraction.

Answer 1

`(2)/(11)`

Explanation:

In the experiment,

Number of Red Beads Picked, n(R)=10

Total Number of Trials, n(S)=10+15+17+13=55

Therefore, the experimental probability that a red bead is selected:

`P(Red)=(n(R))/(n(S)) =(10)/(55)`

`P(Red)=(2)/(11)`
