Answer:
3:50pm
Time Keisha went to the park- 1:30pm
Time spent for hiking- 1hour 35 minutes
Time spent at the picnic area- 45 minutes
1: 30pm
<u>+1. 35mi</u>n
<u> 2: 65pm</u>
But 60 minutes is 1 hour so the 65 will be changed to 1 hour 5 minutes making it
3: 05pm
3: 05pm
<u>+0: 45min</u>
<u> 3: 50pm</u>
Hence the time Keisha left the park was 3:50pm
Answer:
a. 
b. 
Step-by-step explanation:
Theoretical probability is what we expect to happen and experimental probability is what actually happens.
a. In theoretical probability, it doesn't matter what happened in the past. So basically we want to know the probability of rolling a 3 when a number cube is rolled.
There are 6 faces (from 1 to 6) in a number cube. And there is 1 "3". So the probabilty of rolling a 3 is:
1/6
b. In experimental probability, we need to know what happened before. When the cube was rolled 450 times, it came up "3", 67 times.
Hence the experimental probabilty of rolling a "3" is:
67/450
