Answer:
826.8 hours
Step-by-step explanation:
Given data
Lenght of video= 234minutes
number of times watched= 212 times
Based on the information given, we can estimate the number of hours spent watching the video
=234*212
=49608 minutes
in hours
=49608/60
=826.8 hours
in days
=826.8/24
=34.45 days
Answer:
P(B)=0.30
Step-by-step explanation:
Out of 1000 Voters, 30% favor Jones.
Event S=Favors Jones on First Trial
Event B=S occurs on Second Trial
P(S)=0.30
P(S')=1-0.30=0.70
Event B could occur in two ways
- The first two trials are a success
- The first trial is a failure and the second trial is a success.
Therefore,
P(B)=P(SS)+P(S'S)
=(0.3X0.3)+(0.7X0.3)
=0.09+0.21
=0.3
Therefore, the probability of event B(that event S occurs on the second trial), P(B)=0.30.
