Q. You pick a card at random.\newline123123\newlineWhat is P(1 or 2)P(1 \text{ or } 2)?\newlineWrite your answer as a fraction or whole number.\newline_____\_\_\_\_\_
  1. Identify total outcomes: Identify the total number of possible outcomes. There are 33 cards, numbered 11, 22, and 33.
  2. Determine favorable outcomes: Determine the number of favorable outcomes. We need to find the probability of picking a card numbered 11 or 22, so there are 22 favorable outcomes (card 11 and card 22).
  3. Calculate probability: Calculate the probability using the formula P(Event)=Number of favorable outcomesTotal number of outcomesP(\text{Event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}. Here, P(1 or 2)=23P(1 \text{ or } 2) = \frac{2}{3}.

At a science museum, visitors can compete to see who has a faster reaction time. Competitors watch a red screen, and the moment they see it turn from red to green, they push a button. The machine records their reaction times and also asks competitors to report their gender.\newlineThe probability that a competitor reacted in over 0.70.7 seconds is 0.60.6, the probability that a competitor was female is 0.40.4, and the probability that a competitor reacted in over 0.70.7 seconds and was female is 0.30.3.\newlineWhat is the probability that a randomly chosen competitor reacted in over 0.70.7 seconds or was female?\newlineWrite your answer as a whole number, decimal, or simplified fraction.\newline______
