Question 1177238: Diameter 12.0 Frequency 5 , Diameter 13.0 Frequency 11 Diameter 14.0 Frequency 24 ,Diameter 20.0 Frequency 15 ,Diameter 25.0 Frequency ,5?
How do you find the probability of each diameter? P(x)
thank you

You can put this solution on YOUR website!
Look at the relative frequencies
There are 60 such diameters
for diameter 12.0 there are 5, for a relative frequency of 5/60. That is the probability for diameter 12.
Similarly,
for 13.0 the RF is 11/60
for 14.0 the RF is 24.60 or 0.4
for 20.0 the RF is 15/60 or 0.25
for 25.0 the RF is 5/60
The relative frequencies add up to 1, and they must.
