6/20 chance or simplified would be 3/10. Answer [D] is correct.
We know that 75=5*5*3 so
5*5*3 times 5=125*3=375 then move the decimal place two places to the left (divide by 100) and get 3.75
or you could note that 0.75=3/4 so
3/4 times 5=
15/4
simplified=3 and 3/4
-40) No
0) No
-5) No
13) Yes
21)Yes
Answer:
Option D
Step-by-step explanation:
Probability is the likelihood or chance of an event occurring.
Probability = the number of ways of achieving success
/the total number of possible outcomes
For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .
The probability of something which is certain to happen is 1.
The probability of something which is impossible to happen is 0.
The probability of something not happening is 1 minus the probability that it will happen.
By definition we can see that probability lies between 0 and 1 only both inclusive
Hence option D is right.
