Answer 31

take a look at this, the total amount should be 1 . but because you have continues variable the number should have chance to occur. mostly the continues variable density curve doesn't contain steps . because step happens when a number happens for a certain amount. but still I strongly recommend you to check it to be sure. wish you luuk

yea A AND D equal 1 that's why I asked
