Answer:
A.x+5=6x
Step 1:subtract 6x from both sides.
x+5-6x=6x-6x
-5x+5=0
Step 2:subtract 5 from both sides.
-5x+5-5=0-5
-5x=-5
Step 3:divide both by -5
-5x/5=-5/5
X=1
The probability of throwing a multiple of 3 will be or 0.5.
<h3>What is probability?</h3>
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The probability of getting multiple 3 on the side of the six faces die will be calculated as:-
Total outcomes = { 1,2,3,4,5,6} = 6
favourable outcomes = { 2,4,6} = 3
Probability = favourable outcomes ÷ Total outcomes
= 3 ÷ 6
= 1 ÷ 2
= 0.5
Therefore the probability of throwing a multiple of 3 will be or 0.5.

Answer: 0.0000842890
Step-by-step explanation:
Given that :
Number of cards in a deck = 52
Number of hearts in a deck = 13
Probability of being dealt 6 hearts :
Probability = (required outcome / Total possible outcomes)
Required outcome = choosing 6 hearts from a possible 13
13C6:
Recall : nCr = (n! / (n-r)!r!)
13C6 = 13! / (13-6)!6!
13C6 = 13! / 7!6!
13C6 = (13*12*11*10*9*8)/(6*5*4*3*2*1)
13C6 = 1235520 / 730
13C6 = 1716
Total possible outcomes :
52C6 = 52! / (52-6)!6!
52C6 = 52! / 46!6!
52C6 = (52*51*50*49*48*47)/(6*5*4*3*2*1)
52C6 = 14658134400 / 720
52C6 = 20358520
Hence,
P(6 hearts) = 1716 / 20358520
P(6 hearts) = 0.0000842890
