Question in the attachment

Step-by-step explanation:

this is really tricky

so the first pick will make sense

P(m1) 26/46   for pick on.. but that removed one male from the population and also one from the total

P(m2) 25/45

now multiply those two fractions together to get the total probability

26/46 * 25/45 = 650/2070  obviously reduce fraction

65/207= .3140096618

They don't say if you are supposed to use a percent or not

so just try 0.314   :/

X and y are the times in hours that he travelled  on foot and on bus

x + y = 1.5   * by 5:-

5x + 5y  = 7.5
5x + 60y = 35    subtract:-

55y =  27.5
y = 0.5 
and x = 1.5 - 0.5 = 1

so he walked for 1 hour

distance he walked =  average speed * time =  5*1 = 5 miles.
