P(5 on one throw) = 1/8
expected number of 5's in 400 throws = 1/8 * 400 = 50
Answer:
91/216
Step-by-step explanation:
The probability of getting a 4 in the first three rolls is 1 minus the probability of not getting a 4 on any of the rolls.
P(at least one 4) = 1 − P(no 4s)
P(at least one 4) = 1 − (5/6)³
P(at least one 4) = 91/216
Alternatively, you can calculate it this way.
The probability of getting a 4 on the first roll is 1/6.
The probability of getting a 4 on the second roll is (5/6) (1/6) = 5/36.
The probability of getting a 4 on the third roll is (5/6) (5/6) (1/6) = 25/216.
The probability of any of the three events is 1/6 + 5/36 + 25/216 = 91/216.

<h3>What is a statement?</h3>
A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.
Given:
The given statement is the diameter of 3 planet is
planet A= = 1000000000m
planet B==10000000m
planet C= =100000000m
According to given question we have
A dwarf planet is discovered with a radius is 1/100 times of radius of planet C.
Radius of planet C =100000000/2= 50000000m
Radius of dwarf planet = 1/100 times of radius of planet C.
Radius of dwarf planet = 1/100 * 50000000m
Radius of dwarf planet = 500000 m=
Diameter of dwarf planet =2*500000 m=1000000 m=
Therefore, the required diameter of dwarf planet is .

Answer:
Abby's mother spent $9.75 for the classroom not including tax.
Step-by-step explanation:
Know:
5 bags for 1 dollar
10 candy bars for 50 cents
3 whistles for 75 cents
5×6=30
10×3=30
3×10=30
- 5 times 6 is thirty. So find the product of 6 and 1 which is 6. 6 is the overall cost of bags.
- 10 times 3 is 30. So find the product of 3 and .50 which is 1.50. 1.50 dollars is the overall cost of candy bars.
- 3 times 10 is 30. You then find the product of 3 and .75. The product of this is 2.25 which is the total cost of whistles.
- Next you add all the values together which are 6.00 + 1.50 + 2.25 this equals $9.75
