Answer: You would get 20 heads and 20 tails.
Explanation: Assuming that the coin is fair which you said it is, then you can also assume that there’s a 1/2 probability of getting heads each time you flip it and tails each time you flip it. So since you flipped it 40 times, you would assume to get heads 20 times and tails 20 times.
Answer:
At 15:15
Step-by-step explanation:
Given,
the 1st boy can run a lap in 15 minutes
the 2nd boy can run a lap in 25 minutes
the 3rd boy can run a lap in 10 minutes
Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.
of 15,25 & 10 = 150
So,they will pass each other after 150 minutes or 2 hours & 30 minutes.
If we add it with 12:45 we'll get 15:15 or 3:15 pm
