P(John will practice | It rains) * P(It rains) + P(John will practice | It does not rain) * P(It does not rain)
P(John will practice) = 0.8 * 0.6 + 0.4 * 0.4
P(John will practice) = 0.48 + 0.16
P(John will practice) = 0.64
Therefore, the probability that John will practice his cello is 0.64.
P(John will practice) = 0.8 * 0.6 + 0.4 * 0.4
P(John will practice) = 0.48 + 0.16
P(John will practice) = 0.64
Therefore, the probability that John will practice his cello is 0.64.
