The beach!
at the beach 3 kids had a lovely day out. they each saw a different sea creature, each played a different game and they all had something different to eat.
can you figure out which child saw which creature, played which game and ate what item of food?
child: emily, ryan , tyler
animal: crab, starfish, jelly fish
game: cricket, football, kite
food: hot dog, ice cream, lolly
1) ryan did not play cricket, did not see a crab and did not play with a kite
2) the jellyfish was seen by the child that played with a kite
3) tyler did not fly a kite, but did eat a hot dog
4) emily either spotted a jellyfish or she ate an ice cream

the correct answer is 45x

9×5=45 then add the x

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
