Question

1) A dice mubers written on its faces with (1.0, 7.9. 8. 3is thrown, what will be the
Probability of getting a prime number.

2) One acute angle of a right-angled triangle is 22° less than the other acute angle, find the
Measure of its each angle​

Answer 1

Step-by-step explanation:

1) total no of outcomes = 6

total no of favourable cases = 2 ( 7,3 is only prime no )

probability = 2 /6

2) let first angle = x

then second angle = x+22

third angle = 90

x + x+22+90= 180

2x+22+90=180

2x+112=180

2x=68

x=34

second angle= 34+22=56
