A ray of light is incident on a glass slab making an angle of 60° with the surface. Calculate the angle of refraction in glass if the refractive index of glass is 1.5 1) sin-'(1/3)
2) 30°
3) 45°
4) 50°

correct me if i am wrong.

i dont get the question

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
