3 white marbles. the experiment consists of first choosing an urn with equally likely probability, and then drawing a marble from that urn. what is the probability of choosing urn 1 and a white marble?

Hello!

To find the probability of two events, you need to multiply the probability of all the events that make the compound event. In this case, we need to multiply the probability of selecting urn 1 and selecting a white marble from urn 1.

First, we have two urns, so we have a 1/2 chance of selecting urn 1.

Next, we have 16 total marbles in urn 1. If we have 5 white marbles, this gives us 5/16.

Finally, we multiply the probabilities. 1/2(5/16)=5/32.


Our final probability is 5/32, or about 16%.

I hope this helps!

Use the given minimum and maximum data​ entries, and the number of​ classes, to find the class​ width, the lower class​ limits,
Georgia [21]

Answer:

Step-by-step explanation:

Given that minimum is 8 and maximum equals 82

Range = 84-8 = 76

No of classes =6

Class width = 76/6 ~13

But not given whether variable is discrete or continuous.

If discrete, we have classes as

8-20, 21-33, 34-46, 47-59, 60-72, 73-85

If continuous, we have classes as

8 to <21

21 to <34

and ... ending 73-<86
