Total possible outcomes: (2)³=8 (heads or tails possibility on each toss) 

Draw out a Tree diagram to illustrate the given example, labelling the probability on each branch. 

Adding all the possible situations with P(t)≥2, we get 0.352 as the probability. 

Hope I helped :)

Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and n
lana [24]
Let wind speed = x mph 

when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x  = 2 / t -------(1)      where t is the time she took.

when riding with the wind we have 

20 + x = 3 / t--------(2)   adding equations (1) and (2):-

40  =  2/t + 3/t
40 =  5/t
t = 5/40 = 1/8 hr 

x = 20 - 2 / 1/8  = 20 - 16 = 4

Wind speed was 4 mph Answer
