Tamara wants to know how likely her bus is to be late. She records the data over a month and finds it was late on
7 out of 25 times that she went to catch it.
Estimate the probability of the bus being late on any given day.

For any isosceles right triangle two sides are equal and one angle is right angle. therefore it has to be proved with the available data's it the given prism surface is a isosceles right triangle. solution : given hypotenuse is = 50â’â’âš50 cms(43 height of the prism (opp .side) is = 8 cms --2 according to pythagoras theorem ; hypotenuse ^2 = ad -side^2 + opp.side ^2 sub 1 and 2, we get (50â’â’âš50)^2 = ad.side ^2 + 8^2 ad.side^2 = 43 ( forms as base of a isosceles right triangle ) hence the value ad.side = hypotenuse = 43cms to find the area of a triangle, = (1/2) * base * height = 1/2* 43* 8 = 172 cm sq units.
