40% of Pokemon know tackle, 60% know tail whip, and 65% know growl. 25% know tackle and growl, 15% know tackle and tail whip, and 30% know tail whip and growl. 5% know all 3 moves.

draw venn diagram. Draw three circles, each overlapping each other. Label the probabilities in the cricles. 

So the polemon that knows tail whip OR growl=P(tailwhip)+P(growl)+P(both tail whip and growl)=1-(0.6-0.1-0.05)=0.8

let me know if you have any questions thanks
