Answer:
100 minutes
Step-by-step explanation:
First lets find out total how many time they spent on those activities
He spent in driving: 3*60 + 1/4*60=195 minutes
He spent in gardening: 1*60 + 3/4*60=95 minutes
In this way by subtracting from minutes spent during driving to minutes spent during gardening we can know he spent 100 minutes longer
Ta có: P ( A ) P ( B ) = 0 , 12 . Vì P ( A B ) = 0 , 2 ≠ 0 , 12 = P ( A ) P ( B )
nên hai biến cố A và B không độc lập với nhau.
0.05 periodic.
let's do 52/936.
10/33 I hope this helps. Good luck!
