Really need help with this last part

0.64

Step-by-step explanation:

If it is at least one day than it could be once or twice.

multiply to find the probabilities of each day with walking and then add them

WW= 0.6 x 0.1 = 0.06

WB= 0.6 x 0.9 = 0.54

BW= 0.4 x 0.1 = 0.04

Then add these together

=0.64

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
