Answer:
i) 90/150[3/5] ii) 60/150[2/3]
Step-by-step explanation:
SEE PROBABILITY = FAVOURABLE OUTCOMES / TOTAL OUTCOMES
HERE IN i) FAVOURABLE OUTCOME IS 90 BECAUSE WE WANT THE PROBABILITY OF CORRECT FORECASTS
SIMILARLY IN ii) OUR FAVOURABLE OUTCOMES ARE 150-90=60
AND TOTAL OUTCOMES IS 150
HENCE BY USING ABOVE FORMULA WE CAN FIND THE PROBABILITY
(DO NOT FORGET TO REDUCE IT INTO LOWEST TERMS)
HOPE THIS HELPS YOU :)
