The number of boys like to fishing =10
The number of boys enjoy archery =3
The number of boys like hiking =12
The number of boys enjoys carving=1
camping =5 ;carving =1
5+1=6
p(E)=number of favourable outcomes /total number of outcomes
p(E)= \(\frac{6}{15}\)
p(E)= \(\frac{2}{5}\)
Question 12.
Complete the input/output table. Look for a pattern and write the rule.
| Input | 93 | 83 | 73 | 63 | 53 | 43 |
| Output | 74 | 64 | 54 |
Answer:
| Input | 93 | 83 | 73 | 63 | 53 | 43 |

83-19=64
73-19=54
63-19=44
53-19=34
43-19=24 .
