Let us assume that the given speed is in miles per hour.
A race car is driven by a professional driver at 99 mph.
We have to find the speed in kilometer per hour and kilometer per minutes
As 1 mile = 1.61 km
So, 99 miles = kmph
1 km per hour = 0.0166 km per minute
So, 159.39 kmph = km per minute
Hence, The speed is equivalent to 159.39 kilometers /hour, or 2.645 kilometers/minutes .
Answer:
Step-by-step explanation:
Given that from a well shuffled set of playing cards (52 in number) a card is drawn and without replacing it, next card is drawn.
A - the first card is 4
B - second card is ace
We have to find probability for
P(A) = no of 4s in the deck/total cards =
After this first drawn if 4 is drawn, we have remaining 51 cards with 4 aces in it
P(B) = no of Aces in 51 cards/51 =
Hence
(Here we see that A and B are independent once we adjust the number of cards. Also for both we multiply the probabilities)
