Answer:
Total probability (first tile less than 7, second tile multiple of 4) = 2/21
Step-by-step explanation:
The question is not complete as the number of tile are not given. Howover, I could find the complete question on internet so I would solve for that. I hope it helps. (SEE THE ATTACHMENT)
You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. THE PROBABILITY OF CHOOSING A NUMBER LESS THAN 7 AND THEN A MULTIPLE OF 4 IS?
As we can see in the picture that there are a total of 7 tiles, so n = 7
These tiles are numbered as 5, 6, 7, 8, 9, 10, 20
Tiles having a number less than 7 = 5, 6
No. of tiles having a number less than 7 = 2
So probability of choosing a number less than 7 is = 2/7
After picking one tile and without replacing it, total no. tiles become n = 6
Tile having multiples of 4 = 8, 20
No. of tiles having multiples of 4 = 2
Probability of choosing a second tile with multiple of 4 = 2/6
Total probability (first tile less than 7, second tile multiple of 4) = (2/7) · (2/6) = 4/42 = 2/21
