Answer:
m = 1
Step-by-step explanation:
We can suppose that the number we are looking for is for example 5.
(we can do so because the probability is the same for each number - it'sna fair dice)
For the first toss the probability we have 5 is 1/6 (we have 6 numbers on the dice and number 5 is just one of the possible 6 outcomes).
For the second toss the probability we have 5 is again 1/6.
For the rest of 3 tosses we don'tcare what number we will get( we have our two consecutive 5s), so all of the outcomes for the rest of 3 tosses are good for us (probability is 6/6 = 1)
Threfore, the probability to get two consecutive 5s is 1/6 * 1/6 * 1 * 1 * 1 = 1/36.
We can see that m = 1.
Answer:
It's irrelevant.
Step-by-step explanation:
20 theater tickets cost 20T, 16 cinema tickets cost 16C.
Their sum is 20T+16C
You can factor a 4 out of this expression to get 4(5T+4C).
The two expressions are completely equivalent: there is no reason, in general, to prefer 20T+16C or 4(5T+4C).
Sometimes, the exercise may ask explicitly for the factored form.
In other cases, one of the two expression might be more useful: if you had to divide everything by 2, of course it's easier to write
If instead you had to subtract 10T, it would be more useful to write
To recap, 20T+16C and 4(5T+4C) are completely equivalent, and unless you have explicit requests, you may prefer one or the other depending on the calculations you have to do.
