Probability of selecting red tile out of a box containing 3 red,2 white & 5 black tiles = 3/10 = 0.3
Step-by-step explanation:
Probability is the calculation of likelihood of an event.
It can be calculated by Formula : Favourable outcome / Total Outcomes
Example : If a box contain 3 red tiles, 2 white tiles, 5 black tiles
Prob (selecting a red tile) = Favourable outcome (red tiles) / Total Outcomes (total tiles) = 3 / 10 = 0.3
Similarly, prob (white tile) & prob (black tile) = 2/10 ie 0.2 & 5/10 ie 0.5 respectively
It opens down if the lead coefficient is negative
And it shifts to the left by two. Always use the opposite of what is in parenthesis, which in this case is 2.
