Independent events

Two events that happen without influencing the probability of each other occurring are said to be:

• Independent

• Corresponding

• non-independent

• mutually exclusive

Rolling a dice and tossing a coin are:

• Dependent event

• Independent events

Tossing a coin multiple times is a series of:

• Dependent

• Independent

• Complementary events

A dice is rolled.

Which two of these events are NOT independent?

• The number is 2.

• The number is 3.

  
  

• The number is even.

  
  

• The number is 5.

Here are two events.

X: the sky is cloudy

  Answer

  
  

A bag contains eight tiles. Each tile has a letter on it.
The letters are A, C, D, E, G, K, L and N.
A tile is taken from the bag

Two events are:

N: the letter is in the word NECK.

L: the letter is in the word LAND.

Suppose that event N happens: P(L) =

Suppose that event N does not happen: P(L) =

• Independent

• Not independent
