Twelve trophies are baseball, eight are football and five are basketball. At random what is the probability of pulling one basketball and two baseball trophies from boxes
There is a total of 25 trophies.
The probability of randomly pulling a basketball trophy is 5 divided by the numbef of trophies remaining.
The probability of randomly pulling a baseball trophy is 12 divided by the number of trophies remaining.
The probability of randomly pulling a second baseball trophy is 11 divided by the number of trophies remaining.
The probability of the trophies randomly chosen in the order basketball - baseball - baseball is:
5/25 x 12/24 x 11/23 = 0.0478 (approximately)
The probability of the trophies randomly chosen in the order baseball - basketball - baseball is:
12/25 x5/24 x 11/23 = 0.0478 (approximately)
The probability of the trophies randomly chosen in the order baseball - baseball - basketball is:
12/25 x 11/24 x 5/23 = 0.0478 (approximately)
Since all are possible and independent of each other, add those probabilities together to get: 0.143
Twelve trophies are baseball,
eight are football and
five are basketball.
At random what is the probability of pulling one basketball and two baseball trophies from boxes
There are 5 ways of pulling out one basketball
and 12C2 = 66 ways of pulling out 2 baseball ones (12!2!×(12−2)!)=66
Now the total number of ways three trophies can be pulled out is 25C3 =2300
(25!3!×(25−3)!)=2300
So P(1 basketball and 2 baseball) = (5*66)/2300 approx 0.14
5×662300=33230=0.1434782608695652
