Victoria tossed a coin 30 times and got 17 heads.

What is the ratio of heads to coin tosses?
What is the ratio of heads to tails?
What is the ratio of tails to heads?
If victoria tosses the coin 150 times, how many times can she expect to get heads?

What do you think?

heads to coin tosses. She tossed the coin 30 times and got 17 heads, so 17:30. It's 17:30 because it asks heads to coins. heads first, then coins.

What do you think the second one is?

would second be 17:2?

Wouldn't it be 17:13?

To find heads to tails won't you need to subtract 30 - 17 because she tossed the coin 30 times, got HEADS 17 times, and there are only two things she could get, which is heads and tails.. So, 13 tails. That's what I would think

17:13. Does that make sense? It makes sense to me.. if it doesn't seem right to you, then go with 17:2

and the third one I would say

13:17

Like I explained above why I say 13 is tails.

that makes sense, thank you! would last question be divide 150 by 2?

For a fair coin, the number would be 150 * 1/2 = 75

But, we just went through a lot of work to discover that our coin has a probability of 17/30 for getting heads. So, with that coin, 150 tosses should come up with

150 * 17/30 = 85 heads, not 75.

To find the ratio of heads to coin tosses, divide the number of heads by the total number of coin tosses.

Ratio of heads to coin tosses:
Heads / Total coin tosses = 17 / 30

To find the ratio of heads to tails, you need to know the number of tails. Since it was not mentioned, we can calculate the number of tails by subtracting the number of heads from the total number of coin tosses.

Number of tails = Total coin tosses - Number of heads = 30 - 17 = 13

Ratio of heads to tails:
Heads / Tails = 17 / 13

To find the ratio of tails to heads, simply invert the ratio of heads to tails.

Ratio of tails to heads:
Tails / Heads = 13 / 17

Now, to determine how many times Victoria can expect to get heads if she tosses the coin 150 times, we can use the ratio of heads to coin tosses.

Expected number of heads in 150 coin tosses:
Let x be the number of heads in 150 coin tosses.
Thus, x / 150 = 17 / 30

To solve for x, we can cross multiply:
30x = 17 * 150

Divide both sides of the equation by 30:
x = (17 * 150) / 30

Calculating this, we get:
x = 85

Therefore, Victoria can expect to get heads around 85 times if she tosses the coin 150 times.
