Malik wants to find the probability that he and his friend Alyssa will have P.E. as their first elective for the next school year. There are six electives to choose from this school year.Malik designs a simulation where he flips two coins to determine whether he and Alyssa will have PE as their first elective. If the coins land "heads," they will have P.E. first. If the coins land "tails," they will have a different elective first. Malik flips the coins 15 times to calculate the probability they will both have P.E. as their first elective. A better simulation is to change the simulation method to [spinning a spinner with 6 equal sections; just flipping one coin twice; spinning a spinner with 4 equal sections; drawing a card from a deck of 52 cards]Malik should change 15 trials to [75, 30, 10, 50, 5] trials. This will provide results that are closer to the theoretical probability.Using the new simulation criteria, Malik should expect the probability that he and Alyssa will both have P.E. as their first elective to be about [25%, 16.7%, 2.78%, 6.25%]

ANSWER ASAP PLEASEJavier has 3 bags that contained numbered balls.Bag A has balls numbered 1 to 3.Bag B has balls numbered 4 to 6.Bag C has balls numbered 7 to 9.Javier and his friend Mayling make diagrams to represent all the possible outcomes if Javier pulls one ball from each bag. However, when they compared diagrams, they realized that their diagrams were different.Which diagram shows the correct sample space if Javier draws one ball from each bag? Using the correct diagram, how many outcomes are there where at least two balls show an odd number? [8, 16, 10, 12]Using the correct diagram, how many outcomes are there where just one ball is a multiple of 4? [12, 9, 15, 6]

A planned community has 150 homes, each with an automatic garage door opener. The door opener has seven switches that a homeowner can set to 0 or 1. For example, a door opener code might be 1001100. Assuming all the homes in the community are sold, what is the probability that at least two homeowners will set their switches to the same code, and will therefore be able to open each other's garage doors?
