Write of any five pair of events that are complementary.

The measure of an angle is four times the measure of its complementary angle. Then, the measure of that angle is ............

Two dice are thrown together and the total score is noted. The events E, F and G are 'a total of 4', 'a total of 9 or more', and 'a total is divisible by 5', respectively. Calculate P(E), P(F) and P(G) and decide which pairs of events, if any, are independent.

An experiment involves rolling a pair of dice and recording the numbers that come up. Describe the following events : A : the sum is greater then 8. B : 2 occurs on either die C : the sum is at least 7 and a multiple of 3. Which pairs of these events are mutually exclusive ?

For any event A,

In case of a die is getting a 1 complementary to events getting 2, 3, 4, 5, 6? Give reasons for your answer

Out of 100 bulbs in a box 10 bulbs are defective. Five bulbs are selected at random from it. Then find the probability of an event that selected bulb is of without defect.

Two dice are thrown and the sum of the number which come up on the dice is noted. Let us consider the following events associated with the experiment A: 'the sum is even'. B: 'the sum is a multiple of 3'. C: 'the sum is less than 4'. D: 'the sum is greater than 11'. Which pairs of these events are mutually exclusive?
