VLD [36.1K]

Answer:

Outcome = \{4H,4T\}

Step-by-step explanation:

Given

A roll of cube numbered 1 - 4

A flip of coin

Required

Determine the possible outcomes for a number greater than 3

First, we list the sample space of the coin:

Sample\ Space = \{1,2,3,4\}

Next, we list outcomes greater than 3

S = \{3\}

Next, we list out the sample space (C) of a flip of coin:

C = \{H,T\}

Where

H = Head\\T = Tail

So, the possible outcome for a number greater than 3 is:

Outcome = \{4\} + \{H,T\}

Outcome = \{4H,4T\}

14x>-28
Divide 14 on both sides
X<-2
