Two dice are thrown the events A, B, C are as follows A: Getting an odd number on the first die. B: Getting a total of 7 on the two dice. C: Getting a total of greater than or equal to 8 on the two dice. Then AUB is equal to
Let S = set of points inside the square, T = the set of points inside the triangle and C = the set of points inside the circle. If the triangle and circle intersect each other and are contained in a square. Then
$\text{S}\cap\text{T}\cap\text{C}=\phi$
$\text{S}\cup\text{T}\cup\text{C}=\text{C}$
$\text{S}\cup\text{T}\cup\text{C}=\text{S}$
$\text{S}\cup\text{T} = \text{S}\cap\text{C}$
