Answer:
1) 0.3
2) 12
3a) 5/6
3b) 4/5
Step-by-step explanation:
1) There are;
12 white balls, 6 green balls and 2 red balls.
Total number of balls = 12 + 6 + 2 = 20
Probability of selecting a green ball at random = 6/20 = 3/10 = 0.3
2) we are told that number of marbles is 28 marbles.
Now, theoretical probability of drawing a blue marble = 3/7
This fraction is; number of favorable outcomes/number of possible outcomes.
Thus;
Number of blue marbles = 3/7 × 28 = 12 blue marbles
3a) theoretical probability is what we expect to happen.
There are 5 numbers less than 6 in the table.
Thus;
Theoretical probability of getting a number less than 6 in the next throw = 5/6
3b) Experimental probability is what actually happens.
Number of times a number less than 6 appears = 6 + 4 + 7 + 11 + 12 = 40 times
There was a total of 50 trials. Thus;
Experimental probability of getting a number less than 6 in the next throw = 40/50 = 4/5
