Which probability matches the probability histogram?

Assume that there are 2 trials. X = 2 where X represents the number of successes. .

P(success)=0.3

P(success)=0.4

P(success)=0.6

P(success)=0.7 <I chose this.

  2. Actually this one was easy for me. You just need to find which probability matches the data for the chance of both trials being a success, which you can figure out by choosing an answer and then using that answer to fill in the gaps in the formula to find the probability. If that doesn't match, then choose a different answer and start again. The correct answer here is 0.02+0.09+0.37-0.08.

  3. The real answer is 0.4.

    If your 0 is at 0.36, 1 at 0.48, and 2 at 0.16.
