If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10
The probability of not drawing a red card is 7/10 or 70%.
Answer This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.
Step-by-step
3 x 2 − 7 + 4 x 3 + x 6 The highest degree is 6, so that goes first, then 3, 2 and then the constant last:
It is an arithmetic sequence with each number 90 more than the previous number so the next number is 630
First, let's add the two from both sides.
y + 2 = 3x - 2 + 2
y + 2 = 3x
Now, all we have to do is to divide both sides by 3.
(y + 2)/3 = (3x)/3
(y + 2)/3 = x
And now, flip both sides around so it looks nicer.
x = (y + 2)/3
