Question

Three coins were tossed 30 times. Each time the number of heads occurring was noted down as follows:
0 1 2 2 1 2 3 1 3 0
1 3 1 1 2 2 0 1 2 1
3 0 0 1 1 2 3 2 2 0
Prepare a frequency distribution table for the data given above.

Answer 1

Number of Heads                Frequency

0                                            6

1                                             10

2                                            9

3                                            5

Step-by-step explanation:

Number of Heads                Frequency

0                                            6

1                                             10

2                                            9

3                                            5

Total number of  heads = (0 * 6) + (1 * 10) + (2 * 9)  + (3 * 5)

= 0 + 10 + 18 + 15

= 43

Number of tosses = 30

Number of Heads per toss = 43/30

= 1.43
