The probability of getting a 2 and 3 in two cubes is
<u><em>Explanation</em></u>
Total face values in each number cube is 6.
In first cube, probability of getting a 2 is =
and also in the second cube, probability of getting a 3 is =
So, the probability of getting a 2 and 3 in two cubes =
1.-28×-28×-28+13×13×13+16×16×16
=21,952+2,197+4,096
=28,245.
2.12×12×12+-7×-7×-7+-5×-5×-5
=1,728+-343+-125
=1,260

Answer: See explanation
Total number of text messages = 800
Amount used by Tommy and Mary = 1/2 × 800 = 400
Number of messages uses by Jack and Stefanie = 240
The expression to find the number of messages Cathy uses will be:
= 800 - (1/2 × 800) - 240
Since the expression is 800 - (1/2 × 800) - 240, the number of messages that Cathy will use will be:
= 800 - 400 - 240
= 160 messages
