Answer:
P(rolling five distinct values) = 1/3888
Step-by-step explanation:
We are told that I the fair sided dice, 6 is replaced with 5.
Thus,the numbers are now;
1,2,3,4,5,5.
This means a total of 6 possible numbers appearing.
Now, in these 6 numbers there are only 5 distinct numbers since 5 occurs twice.
P(1) = 1/6
P(2) = 1/6
P(3) = 1/6
P(4) = 1/6
P(5) = 2/6
Thus,probability of rolling 5 distinct values = 1/6 × 1/6 × 1/6 × 1/6 × 2/6 = 1/3888
Answer:
2.50
Step-by-step explanation:
30% of 25 is 7.50 take that away from 25 gives you 17.50 take that away from 20 gives you 2.50
We want to solve the equation :

first, multiply both sides by 4:


divide both sides by 3:

add -3 to both sides:

Answer: x=9
