Step-by-step explanation:
84o students would be expected to play outdoor games for at least three hours every week.
The sample showed that 70% students played outdoor games for at least three hours every week. 70% of 1,200 is 840.

How many different combinations can you make?</h3>
To find the total number of combinations, we need to find the number of options for each one of the digits.
There are 4 digits, such that each digit can only be an odd number.
- For the first digit, there are 5 options {1, 3, 5, 7, 9}
- For the second digit, there are 5 options {1, 3, 5, 7, 9}
- For the third digit, there are 5 options {1, 3, 5, 7, 9}
- For the fourth digit, there are 5 options {1, 3, 5, 7, 9}
The total number of different combinations is given by the product between the numbers of options, so we have:
C = 5*5*5*5 = 625.
There are 625 different 4-digit codes only made with odd numbers.

Answer:
0.06
Step-by-step explanation:
Given that :
Average number of road accident (n) = 11
Probability of observing exactly 7 accident o. The stretch of road next year
Poisson random variable (k) = 7
Using the poisson distribution formula :
P(x = k) = (n^k * e^-n) / k!
P(x = 7) = (11^7 × e^-11) / 7!
P(x = 7) = (19487171 × 0.0000167017) / 5040
P(x = 7) = 325.4688838907 / 5040
P(x = 7) = 0.0645771
= 0.06
