The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%

Answer:
102 km/hr
Step-by-step explanation:
Formula: ![Speed=\frac{distance}{time}](https://tex.z-dn.net/?f=Speed%3D%5Cfrac%7Bdistance%7D%7Btime%7D)
The distance = 85 km, and the time elapsed = 50 mins
Speed = 85/50 = 1.7 kilometers a minute
To find out the speed per hour, we multiply by 60
1.7 * 60 = 102
The speed is 102 km/hr
