b)0.375
Step-by-step explanation:
Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6
Even= 2,4,6
Odd = 1 ,3 , 5
Probability of getting even =
Probability of getting odd =
4 dices are rolled together
a)P(3 even and 1 odd numbers)
P(3 even and 1 odd numbers)=
P(3 even and 1 odd numbers)=
b)P(2 even and 2 odd numbers)
P(2 even and 2 odd numbers)=
P(3 even and 1 odd numbers)==0.375
Answer:
Water level after 24 hours will be .
Step-by-step explanation:
Given:
Evaporate rate of water= 0.005 inches per hour.
We need to find the level of water after 24 hours.
now we know the in 1 hour the water evaporates from a pool at a rate of 0.005 inches.
So To find the water level after 24 hrs we will multiply the evaporation rate with total number of hours which is 24 and the divide by 1 hour we get.
Framing in equation form we get;
water level after 24 hrs =
Now to convert the number in rational form we have to multiply and divide the number by 100 we get;
Hence Water level after 24 hours will be .
