A dice is rolled 360 times and the results are recorded as follows: 60 ones 58 twos 70 threes 74 fours 38 fives and 60 sixes
What is the experimental probability of rolling a two or a three?
A. 0.11 B. 0.36. C. 0.14. D. 0.64

58+70=128.  60+58+70+74+38+60=360.  128/360=0.356=0.36

Step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the answer is d on edge
