The probability of getting all heads is 1 / 2^6 = 1/64 as there is only 1 event where this happens in a possible 2^6 = 64 events. It is the same as the probability of getting all tails. The probability of getting at least 1 head is 1 - p(all tails) = 63/64.
If a square contains 171 tiles you will need multiply 21 by 171 (171x21) which should give you the amount for the entire roof.
Hope this helps! :)
The answer is D to your answer. Have a wonderful Day. Brainly.
Slope is rise/run
gains 4m height for every 3secons
rise=4m
run=3sec
slope=4/3
if takes 54seconds t
54 times 4/3=72 meters
max height is 72 meteres assuming that it starts from the ground level
