The above table shows the number of people visiting the Good-living pavilion in a trade fair during different time of the day.

Find the probablity that the randomly chosen person visited the pavilion.

1. after 1pm but before 5pm

2. between 9am to 1pm

3. after 5pm

4. between 3pm and 5pm.

Please answer this question urgently. My exam is on 20th Thursday.

Thanks

1. Probability = 225 + 200/835 = 425/835 = 85/167

2. Probability = 300/835 = 60/167

3. Probability = 120/835 = 24/167

4. Probability = 200/835 = 40/167

Good Luck

P(after 1pm but befor 5pm) = 425/835

= 85/167

P ( between 9am to 1pm ) = 300/835

=60/167

P {after 5 pm } = 120/835

=24/167

P{between 3 pm and 5pm } = 200/835

=40/167

HOW DID YOU GET 835?

THANKS

It is 845 not 835. because 175+125+225+200+120=845

1. Probability = 225 + 200/845

2. Probability = 300/845

3. Probability = 120/845

4. Probability = 200/845
