A bag contains 14 green tiles,10 red tiles, and 16 blue tiles. Brodie randomly draws a tiel, records the color , and replaces the tile. if he does this 80 times, how many times should he expect to draw a red tile

20 red tiles

Step-by-step explanation:

14 green tiles,10 red tiles, and 16 blue tiles. = 40 tiles

P(red) = 10/40 = 1/4

If we draw 80 tiles

80 * 1/4 = 20

We should expect 20 red tiles

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
