Find the probability of getting a prime number in single throw of a dice

1 answer:

6 0

We find this number by multiplying 6 x 6. The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12 (E).

1 km / 5 mins

Convert 1 km to meters:
1000 m / 5 mins

Divide by 5 on both sides:
200m / 1 min

Convert 1 min to seconds:
200m / 60 sec

Divide by 60 on both sides
3.33m / sec (nearest hundredth)

Answer: Matty's speed is 3.33m/s

A MILKMAN SOLD TWO OF HIS BUFFALOES FOR RS.20,000. EACH ON ONE HE MADE A GAIN OF 5% AND ON THE OTHER A LOSS OF 10%. FIND HIS OVE

Sveta_85 [38]

Selling price of 1st buffalo +Selling price of 2nd buffalo=20000
profit for 1st buffalo=0.05 of cost price of 1st buffalo
loss for 2nd buffalo=0.1 of cost price of 2nd buffalo
1.05(cost price of 1st buffalo)+(0.9)cost price of 2nd buffalo=20000
the buffalo must cost must be same = x (say)
1.05x+0.9x=20000
1.95x=20000
x=10256.41
2x=20512.82
profit=20512.82-20000=512.82
profit %=2.56410 %
