Answer:
1.1/4
2.3/4
3.1/4
4.1/4
5.1/2
Step-by-step explanation:
All the possibilities are 1,2,3,4. Four possibilities
1) There in only one situation in which 4 occurs,
probability in 1 ÷ 4=1/4
2) There are tree situation in which 1,2 And 3 occur.
Probability in 3 ÷ 4=3/4
3) There in one case where 1 appears
Probability is 1 ÷ 4 =1/4
4)There in only one situation in which 3 occurs,
The probability in 1 ÷ 4=1/4
5)There are 1 and 3 odd numbers.
The probability is 2 ÷ 4=1/2
Invistigate the possibility
