what is this probability if the trials were in the united states? (round your answer to three decimal places.)

(b) of the six trials, what is the expected number of guilty verdicts in japan? (round your answer to two decimal places.)

what is the expected number in the united sates? (round your answer to two decimal places.)

Total cost of croissants produced = $1.75 x 300 = $525

Total expected revenue = (100 + 45%)/100 x $525 = 1.45 x 525 = $761.25

Number of croissants expected to spoint = 0.10 x 300 = 30 croissants.

Number of croissants sold = 300 - 30 = 270 croisants.

Unit price of each croissant = $761.25/270 = $2.82

Therefore, each croissant should sell for $2.82
