216 divided by 3 is 72 so making the answer
1/72
Answer:
yes
Step-by-step explanation:
yes you can
Okay well the way I do it is like this. When ever the next hour hits 10 minutes that is one hour then add the minutes left. So from 7:10a.m. to 6:10p.m. is 11 hours. Now the rest of the minutes. 6:35 -6:10=:25. So she has been away from the house for 11 hours and 25 minutes
Total marbles in the bag = 15
Red marbles in the bag = 5
Probability of picking a red marble the first time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the second time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the third time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the fourth time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the 20th time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the ' Nth ' time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble ' N ' times in a row = (5/15)^N.
Probability of picking a red marble 3 times in a row = (5/15) (5/15) (5/15).
Probability of picking a red marble 2 times in a row = (5/15) x (5/15)
= (25/225) = 1/9
= 11.1% (rounded).
1 hour and 45 minutes is 105 minutes... that's our start.
The formula for speed is distance divided by time. Plugging our data in, we have S=18.25/105, which is 10.4826 km/h, to find kilometres a minute, we need to divide our answer by 60. Our answer is 0.17471 km/m
