In a local fitness club 32% of the members lifted weights, 41% preferred aerobics
In a local fitness club 32% of the members lifted weights, 41% preferred aerobics and 6%preferred both.if a member is chosen at random, find the probability that the member prefers another method neither weights nor aerobics to exercise
Members lifted weights: W=32% Members preferred aerobics: A=41% Members preferred both: B=6% Members lifted weights only: Wo=W-B=32%-6%→Wo=26% Members preferred aerobics only: Ao=A-B=41%-6%→Ao=35% Find the probability that the member prefers another method neither weights nor aerobics to exercise: N=?
N=100%-Wo-Ao-B N=100%-26%-35%-6% N=100%-67% N=33%
The probability that the member prefers another method neither weights nor aerobics to exercise is 33%
