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:

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

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

6x-21>3 and 14x+11>-17

Delicious77 [7]

6x-21>3
Add 21 to both sides
6x>24
Divide 6 on both sides
X>4

14x+11>-17

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