The probability of the first event with x possible outcomes is equal to x/30. Also, the probability of the second event with y possible outcomes is y/29.
(1) P of 2 digit number, 21/30
P that the number is 4 is 1/29
Multiplying both probabilities will give us 7/290
(2) P that number is 19 is 1/30
P that the number is multiple by 4 is 6/29
The answer is 1/145
(3) P that number is 24 is 1/30
P that number is less than 15 is 14/29
The answer should be 7/435.
(4) P that number 1st number is perfect square is 5/30
P that second number is perfect square is 4/29.
The answer is 2/87.

Answer:
Step-by-step explanation:
20.1metres / seconds
We want to convert to metres /minutes
It is known that 60seconds=1minutes
So therefore, either we multiply 20.1metres/seconds by
60seconds/1minutes
Or
1minutes/60seconds
Multiplying with the above does not change the magnitude of the quantity because it is like we are multiplying by 1.
Since we want to cancel seconds and it is in the denominator, so to do this we need to multiply with the fraction that has the seconds as numerator.
So, we are going to multiply with 60seconds/1minutes
20.1metres/seconds ×60seconds/minutes
1206metres/minutes.
So the correct fraction is the StartFraction 60 seconds Over 1 minute, which is the third option
