You are determining the efficacy of a new cancer treatment for a cancer with a survival rate of 20%. You place 25% of participants into the control group which will receive no treatment, and 75% in the treatment group. You find that those who receive treatment have a 40% chance of survival, a significant increase from the 20% survival observed without treatment! What was the probability of survival for participants who enrolled in your study? Your answer should be in decimal format out to two decimal places (e.g., 0.00)
