Answer:
2 / 13
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of 4's = 4 ( 1 for each suit)
Number of 6's = 4 (1 for each suit)
Probability, P = required outcome / Total possible outcomes
P(a 4) = 4 / 52 = 1/ 13
P(a 6) = 4 /52 = 1/13
Probability of either a 4 or a 6
P(a 4) + P(a 6)
1/13 + 1/13
= 2 / 13
x=(13±3√17)/2x
≈ 12.68465843, 0.31534156
Which would be 12.7 and 0.3 If you rounded to the nearest tenth.
Answer:
I think the answer is 1/9
Step-by-step explanation:
I did the equations by using a tree diagram to explain it but
Answer:
x = 20
Step-by-step explanation:
x/4 - 1 = 4
Since to find x it has to be made the the subject
x/4 = 4+1
x/4 = 5
x = 5×4
x =20
